Standard Single Thread U-Nuts

Palnut lock nuts incorporate a design principle that has stood the test of over 60 years. These nuts may be used alone for load-carrying in light-duty assemblies or they may be used on top of ordinary nuts to assure tightness of high-stress assemblies. They offer impressive savings over alternative fasteners in initial cost, assembly time, weight and space. They are removable, reusable, self-cleaning. They are unaffected by temperatures up to 400°.
